Sinecologia e inventário forrageiro para manejo participativo de agroecossistema de base familiar.

Resumo: O estudo foi conduzido para avaliar as características estruturais e a produção de matéria seca no manejo participativo de agroecossistema de base familiar. Foi usada a amostragem sistemática, em sistema agroflorestal conhecido como quintal produtivo. A cobertura do solo, a frequência para gramíneas, leguminosas e outras espécies e a produção de fitomassa foram mensuradas. A cobertura do solo pela vegetação foi de 18%, as frequências para gramíneas, leguminosas e outras espécies foram, respectivamente, 81, 43 e 88% e a estimativa de produtividade de fitomassa do agroecossistema foi de 2.720 kg de MS ha-1. Com os resultados gerados, foi promovida a troca de saberes entre técnicos e agricultores na tomada de decisão sobre o manejo do agroecossistema. As variáveis estruturais quantitativas, cobertura do solo pela vegetação e frequência de grupos de espécies, com a variável produção de fitomassa podem ser usadas de forma participativa na avaliação e determinação de manejo e monitoramento de agroecossistemas de base familiar. Estudos complementares são recomendados integrando medidas quantitativas com qualitativas. [Synecology and forage inventory in participatory management of family-based agroecosystems]. Abstract: The study was conducted to evaluate the structural characteristics and dry matter (DM) production in participatory management of family-based agroecosystems. Systematic sampling was used in agroforestry system known as home gardens. The soil cover, the frequency for grasses, legumes and other species and biomass production were measured. The soil cover vegetation was 18%, the frequencies for grasses, legumes and other species were, respectively, 81, 43 and 88% and the estimated biomass productivity of the agroecosystem was 2720 kg DM ha-1. With the results, was promoted the exchange of knowledge between technicians and farmers in decision-making about agroecosystem management. Quantitative structural variables, ground cover vegetation and frequency of species groups, with variable biomass production can be used in a participatory manner in the evaluation and management and monitoring of family-based agroecosystems. Additional studies are recommended integrating qualitative with quantitative measures

Electromagnetically induced transparency and dynamic Stark effect in coupled quantum resonators

In this work we reproduce the phenomenology of the electromagnetically induced transparency and dynamic Stark effect in a dissipative system composed by two coupled bosonic fields under linear and nonlinear amplification process. Such a system can be used as a quantum switch in networks of oscillators

The Utility of Capsicum annuum L. in Internal Medicine and In Dentistry: A Comprehensive Review

Capsaicin is a chili peppers extract, genus Capsicum, commonly used as a food spice. Since ancient times, Capsaicin has been used as a "homeopathic remedy" for treating a wild range of pathological conditions but without any scientific knowledge about its action. Several studies have demonstrated its potentiality in cardiovascular, nephrological, nutritional, and other medical fields. Capsaicin exerts its actions thanks to the bond with transient receptor potential vanilloid subtype 1 (TRPV1). TRPV1 is a nociceptive receptor, and its activation starts with a neurosensitive impulse, responsible for a burning pain sensation. However, constant local application of Capsaicin desensitized neuronal cells and leads to relief from neuropathic pain. In this review, we analyze the potential adjuvant role of Capsaicin in the treatment of different pathological conditions either in internal medicine or dentistry. Moreover, we present our experience in five patients affected by oro-facial pain consequent to post-traumatic trigeminal neuropathy, not responsive to any remedy, and successfully treated with topical application of Capsaicin. The topical application of Capsaicin is safe, effective, and quite tolerated by patients. For these reasons, in addition to the already-proven beneficial actions in the internal field, it represents a promising method for the treatment of neuropathic oral diseases

Abordagem multivariada para recomendação de sorgo forrageiro no semiárido cearense.

A decisão de quais culturas forrageiras plantar nas regiões semiáridas brasileira não é um processo fácil, devido as instabilidades climáticas decorrente em cada safra agrícola. Dessa forma, o presente trabalho objetivou-se comparar o desempenho fenotípico de cultivares híbridas e variedades da cultura do sorgo para a produção de forragem com o auxílio do método gráfico para análise multivariada, em região norte cearense. O ensaio foi conduzido envolvendo cultivares tanto de variedades (V) quanto de híbridos simples de sorgo. O delineamento experimental utilizado foi o de bloco ao acaso com três repetições. Foram avaliados 17 caracteres pela análise de variância e posteriormente analisadas pelo método gráfico com análise multivariada, que permitiu uma melhor decisão sobre o desempenho entre as cultivares da cultura quando se consideram grandes quantidades de caracteres. As cultivares de sorgo hibrido BRS 716 e o sorgo BRS 655 apresentam bom desempenho produtivo e nutricional em condições de semiárido

Brown dwarf census with the Dark Energy Survey year 3 data and the thin disc scale height of early L types

27 pages, 18 figuresIn this paper we present a catalogue of 11 745 brown dwarfs with spectral types ranging from L0 to T9, photometrically classified using data from the Dark Energy Survey (DES) year 3 release matched to the Vista Hemisphere Survey (VHS) DR3 and Wide-field Infrared Survey Explorer (WISE) data, covering ≈2400 deg2 up to iAB = 22. The classification method follows the same phototype method previously applied to SDSS-UKIDSS-WISE data. The most significant difference comes from the use of DES data instead of SDSS, which allow us to classify almost an order of magnitude more brown dwarfs than any previous search and reaching distances beyond 400 pc for the earliest types. Next, we also present and validate the GalmodBD simulation, which produces brown dwarf number counts as a function of structural parameters with realistic photometric properties of a given survey. We use this simulation to estimate the completeness and purity of our photometric LT catalogue down to iAB = 22, as well as to compare to the observed number of LT types. We put constraints on the thin disc scale height for the early L (L0–L3) population to be around 450 pc, in agreement with previous findings. For completeness, we also publish in a separate table a catalogue of 20 863 M dwarfs that passed our colour cut with spectral types greater than M6. Both the LT and the late M catalogues are found at DES release page https://des.ncsa.illinois.edu/releases/other/y3-mlt.Peer reviewedFinal Published versio

Traumatic Pseudoaneurysm of the Internal Maxillary Artery: A Rare Life-Threatening Hemorrhage as a Complication of Maxillofacial Fractures

Pseudoaneurysm of the internal maxillary artery due to a traumatic event is a rare condition. Pseudoaneurysms are usually directly produced by arteries break with extravasation of blood. The compressed perivascular tissue forms the wall of aneurysmal sac. Then, this sac gradually expands and can be damaged. It is rare to see pseudoaneurysms of IMA. They are usually associated with fracture of the neck of the mandible. To the best of our knowledge the pseudoaneurysm of the internal maxillary artery related to maxillofacial trauma is an event extremely rare in the literature and if not quickly managed can lead to the patient’s death. This case underlines how the close cooperation between surgeons and radiologists results in a quick diagnosis and management of such pathological events
